My son had a smallish boil on his knee. It just didn't look good so I took him to the doctor. They said it was probably staph and to give him Keflex four times daily and use moist compresses. Well, it is worse. his knee is all swollen and puss keeps draining out. It has been less then 24 hours on the medicine. He does NOT have a fever or red streaks. I am concerned due to it being on his knee of joint involvement. Have you ever experienced this and what do I do??
